Hi bbwish,
I am not a TCC buddy and I don’t want to get your hopes up in the wrong way but I was getting a really yucky discharge and it was rather stinky, much different to the 'usual' discharge... I went to the doc and she did a pregnancy test and it came up negative..... so then she did a few tests for the most horrible things like gonnaria, Chlamydia and a few other charming things.... when I went back to get the results I was a week late for my period and did a test to find that i was pregnant!!!

So it was in fact the mucus forming the mucus plug!
I then had some pretty bad cramping for a few weeks and the doc told me that was just my little man attaching himself to the walls of the uterus

So I really hope that is the case for you!! If not, forgive my foot in mouth
